Contrary to popular belief, blue, green, and slotted weapons do not have a lower chance of refinement success. It has the exact same rates of success as other weapons. It's because that they're rarer that it's harder to find a good refined blue/green weapon. Wan Daye weapons are a good way to dispell this belief. If the blue, green, slotted rule was followed, Wan Daye weapons break this rule because according to the people who follow this belief, it should be easier to refine than blue weapons or weapons with slots yet they consider it the hardest to refine.

The appearance of the weapon's refinement color depends on the weapon you use. Fists and bracers just cover the entire hand. Wheels glitter instead of glow.
